Former Arsenal manager Arsene Wenger regretted his decision to snub a move to Real Madrid to remain with Arsenal during his prime days which has cost him success in his career.
Wenger went on to spend 22 years at Arsenal, winning just three Premier League titles in his early stages and went 14 years with lifting the Premier League.
The French tactician admits that he regrets turning down such a move on numerous occasions, acknowledging that he would have won more trophies if he'd left.

He told Bein Sports 'Regret is that maybe I sacrificed a little bit the winning potential against the loyalty potential. Or the desire to build up the club and the influence I had on the club.
'To build up the club when we built the stadium, against the fact that I could have won more by going somewhere else and being less limited financially. At the end of the day, I'm happy to do what I did.'
The Frenchman did win seven FA Cups alongside his three league triumphs, as well as seven Community Shields, but there will always be an element of disappointment that the club's last Premier League win came in 2004.
Despite that, Wenger is proud of his time in north London and even questions whether his style would have worked at Real Madrid.
'I thought from a very young age I want to work the way I like to work,' he added. 'Sometimes today I weigh up a little bit "have I done well or not?".
'But I felt that I was in a club [Arsenal] where I met my needs the way I wanted to work.
'Why change that and maybe be in a bit more glorious situation but less happy situation, where I had less influence on the club [Real Madrid]? So I decided that I keep trying to experience my love story [at Arsenal].'
